I went with electric vests. My wife loves it. We've done big trips to the Sierra's in 30 degree temps with comfort to spare. We wear a base layer then the vest then a light polar fleece top then a jacket. We have ski hats and gloves. By keeping your body core warm your extremities stay warmer easier. It's a lot easier than taking your seat apart. The vests have individual rheostats to control the heat. They don't pull much amps
